Water Washable Red Photosensitive Pad Printing Polymer Plate
Application:
One of the key factors to pad printing a perfect image is having a well-made printing plate.Along with development of technology,more and more people like water polymer plate instead of steel cliche, because polymer plates is more convinient in making process, it’s save much more time than making one steel plate. as we known,traditionally the plates are generally of thick steel material which is made by a very special process of hardening and etched by chemical milling process. make one steel plate for pad printing, you need many chemicals,like emulsion,engrave liq,etc.you even use one coating machine to coat the emulsion, and the process is very complex, it’s hard to operation for starter. but now, you just use one polymer plate to make pad printing plates, say goodbye to any chemicals and complex operation forever!
A polymer plate is type of printing plate with a photosensitive coating. This coating changes in chemical composition when exposed to ultraviolet light (UV). The printing plate holds the etch (image). The image then is transferred to the substrate using a printing pad (printing tampon).
Features:
Water washable photosensitive polymer material
Steel carrier with a photopolymer layer on top
Exceptional durability and image reproduction.
Withstand up to 75,000 impressions
Simple to make without the use of agressive chemicals,special for starter.
Suitable for various of ink cup,like magnetic ink cups and mechanical pressed ink cups
Printing times: Withstand up to 75,000 impressions.
Easy To Step:
1.Remove the cover film and place a negative film on the undeveloped plate. 2.Expose the plate through the negative film by LED UV exposure unit. 3.Remove the negative film. 4.Second expose the plate through the yeld film by LED UV exposure unit. 5.Washout the exposed plate with water or alcohol (depending on your plate type). 6.Dry the plate in a hot-air dryer after taking off the surface water with a sponge roll. 7.Drying time depends on the type of plate. 8.Expose the developed plate after drying again to UV light in order to get stability. 9.Ready to print.
Which factors can affect photopolymer plate depth?
Type of plate material
Line screen density of yeld film
Exposure time
To create a “dot patterns” or “walls”, use a line screen for the second exposure.
Exposure through the line screen allows a controlled amount of light through the clear holes of the screen. This will “cure or harden” the image area that was previously protected from the UV light during the first exposure.
Line screens vary in lines and percentages. For example 80L90% vs 120L90%. The 80L90% screen will etch deeper than the 120L90%. Therefore, when printing on products like textiles, parts with a textured surface or when printing a lighter color ink on a darker color part we recommend the 80L90% screen.
